If you are talking about non-GPS quads I see your point (although the one in your picture looks otherwise). But how a beginner can crash a GPS located quad is beyond me. Take off straight up, put it above the tree line and, if you get disoriented, let go of the controls. Now, when you think you are good (read "cocky") I can see getting into sticky situations. The bottom line is, since this is a P3 forum, any talk of damaged props means a very real possibility of a damaged gimbal and/or camera - a much costlier issue.I buy the cheap props for my other quadcopters i built, so that I can teach others to fly before they purchase an expensive quadcopter. They crash these all the time.
